Charlie Sheen (anyone doubting his acting chops - go back and watch Platoon or Wall Street.) He makes sense in the same way RDJ did for Iron Man. His career hit the skids as a result of substance abuse, but he has the gravitas and acting chops to pull off Strange. And like RDJ, if the film is done right and he nails it, it will become the next pivotal franchise for Marvel during the Phase III and beyond years.
